"The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016."

Detailed Information

Field Name

Field Value

Field Description

LOINC Number

48049-1

The unique LOINC Code is a string in the format of nnnnnnnn-n.

Component

Eosinophils

First major axis-component or analyte

Property

PrThr

Second major axis-property observed (e.g., mass vs. substance)

Time Aspect

Pt

Third major axis-timing of the measurement (e.g., point in time vs 24 hours)

An arbitrary classification of the terms for grouping related observations together. The current classifications are listed in Table 29. We present the database sorted by the class field within class type (see field 23). Users of the database should feel free to re-sort the database in any way they find useful, and/or to add their own classifying fields to the database.
The content of the laboratory test subclasses should be obvious from the subclass name.

VersionLastChanged

2.56

The LOINC version number in which the record has last
changed. For new records, this field contains the same value as
the loinc.FirstPublishedRelease field.

ACTIVE = Concept is active. Use at will.
TRIAL = Concept is experimental in nature. Use with caution as the concept and associated attributes may change.
DISCOURAGED = Concept is not recommended for current use. New mappings to this concept are discouraged; although existing may mappings may continue to be valid in context. Wherever possible, the superseding concept is indicated in the MAP_TO field in the MAP_TO table (see Table 28b) and should be used instead.
DEPRECATED = Concept is deprecated. Concept should not be used, but it is retained in LOINC for historical purposes. Wherever possible, the superseding concept is indicated in the MAP_TO field (see Table 28b) and should be used both for new mappings and updating existing implementations.

Class Type

1

1=Laboratory class; 2=Clinical class; 3=Claims attachments; 4=Surveys

Units Required

N

Y/N field that indicates that units are required when this LOINC is included as an OBX segment in a HIPAA attachment

This is a new field introduced in version 2.05. It contains synonyms for each of the parts of the fully specified LOINC name (component, property, time, system, scale, method). It replaces #8, Relat_NMS.

Short Name

Eosinophil Stl Ql Wright Stn

Introduced in version 2.07, this field is a concatenation of the fully specified LOINC name. The field width may change in a future release.

Order OBS

Both

Defines term as order only, observation only, or both. A fourth category, Subset, is used for terms that are subsets of a panel but do not represent a package that is known to be orderable we have defined them only to make it easier to maintain panels or other sets within the LOINC construct.

Long Common Name

Eosinophils [Presence] in Stool by Wright stain

This field contains the LOINC term in a more readable format than the fully specified name. The long common names have been created via a table driven algorithmic process. Most abbreviations and acronyms that are used in the LOINC database have been fully spelled out in English.

Change Reason

"The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016."
